The Survey for the Effect of Guideline about Activities of Daily Living in Dementia Patients "Il-sang-ye-chan" Campaign

BACKGROUND: Activities daily living (ADL) disability has a direct influence on the patients' quality of life and on the amount of care needed. It is major factor of care in dementia patients. So Korean Dementia Association suggested guideline about activities of daily living in dementia patients in 2013. The purpose of this article is to investigate the effect of this. METHODS: A total of 110 subjects were enrolled. Assessments included age, sex, education level of patients and caregiver, the duration of disease, pattern of family, economic status. We divided "active practice" group and "passive practice" group by recognition of guideline contents after study. We compared two groups before and after by Korean Mini-Mental State Examination (K-MMSE), Short form of Geriatric Depression Scale-Korean version (S-GDS), Korean version of Zarit's Burden Interview (ZBI-K), Alzheimer's Disease Cooperative Study-Activities of Daily Living scale (ADCS-ADL). Finally, we investigate the level of satisfaction about our guideline. RESULTS: Age of patients, the duration of disease was lower and education level of caregiver and economic status was higher in "active practice group". The pattern of family also differed from two groups. It was observed distinct difference between the variations of two groups in S-GDS, ZBI-K, and ADCS-ADL. The level of satisfaction about our guideline was very high. CONCLUSION: Considering these results, our guideline about activities of daily living is effective to manage dementia patient. Active application of it is needed in clinic or center for dementia.

Dissemination of CTX-M Type Extended-Spectrum beta-Lactamases and Emergence of CTX-M-12 in Escherichia coli / 대한진단검사의학회지

BACKGROUND: Clinical isolates of Escherichia coli were evaluated to determine the prevalence and genotypes of Ambler class A extended-spectrum beta -lactamases (ESBLs). METHODS: Clinical isolates of E. coli were collected from 12 hospitals from February through July, 2004. Antimicrobial susceptibility was tested by disk diffusion and agar dilution methods, and ESBLproduction was determined by double-disk synergy test. TEM, SHV, CTX-M, PER-1, VEB, IBC, GES, and TLA type ESBL genes were detected by PCR amplifications, and the PCR products were subjected to direct sequencing. RESULTS: The double-disk synergy test was positive in 90.9% (149 in 164) of the ceftazidime- or cefotaxime-resistant E. coli isolates. The most prevalent types of Ambler class A ESBLs in E. coliisolates were CTX-M-15 (n=53). CTX-M-14 (n=24), CTX-M-3 (n=9), CTX-M-9 (n=3), CTX-M-12 (n=3), SHV-2a (n=1), SHV-12 (n=5) and TEM-52 (n=3) were also found. CTX-M-12 ESBL had never been reported before in Korea. CONCLUSIONS: CTX-M type ESBL-producing E. coli isolates are spreading and CTX-M-12 is emerging in Korea.

Interictal Motor Cortex Excitability in Migraine and Chronic Tension Type Headache using Transcranial Magnetic Stimulation

BACKGROUND: The pathophysiology of migraine is only partly understood. Transcranial magnetic stimulation has been developed to study cortical physiology noninvasively. Chronic tension-type headache has not been studied with transcranial magnetic stimulation. Among other hypotheses, it has been proposed that interictal hypoexcitability could be partly responsible for the migraine. METHODS: Patients were divided into three groups: normal subjects(n=30), migraine with(n=11) or without aura(n=19) and chronic tension-type headache(n=30) according to the International Headache Society criteria. We studied cortical excitability between normal subjects and patients with migraine with or without aura and between normal and patients with chronic tension-type headache. RESULTS: The mean amplitude of cortex and spinal cord for normal subjects was 3.76 +/-1.74 mV, 2.03 +/-1.54 mV(abductor digiti minimi muscles, respec-tively) and 2.99 +/-2.04 mV, 3.88 +/-3.89 mV(abductor hallucis muscles, respectively). The mean amplitude of cortex and spinal cord for migraine with aura or without aura was 2.16 +/-1.21 mV, 0.90+0.80 mV(abductor digiti minimi muscles, respectively) and 1.88 +/-1.23 mV, 2.31 +/-2.25 mV(abductor hallucis muscles, respectively). The mean amplitude of cor-tex and spinal cord for chronic tension-type headache was 1.61 +/-0.50 mV, 0.72 +/-0.32 mV(abductor digiti minimi mus-cles, respectively) and 1.54 +/-0.55 mV, 1.51 +/-0.59 mV(abductor hallucis muscles, respectively). The amplitude of motor evoked potentials of cortex and spinal cord in migraine and chronic tension-type headache showed significant decreases compared to normal subjects( p < 0.001). CONCLUSIONS: These results are explained by cortical and spinal hypoexcitability in migraine and chronic tension-type headache. We suggest that enhanced serotonergic activity could be some rule for cortical hypoexcitability.

A Neuronal Hyper-responsiveness in PRVEPs of Migraine Patients

BACKGROUND: Although a number of visual evoked potentials (VEPs) studies have been performed to elucidate the pathophysiology of migraines, their results have been controversial. We studied the pattern-reversal visual evoked potentials (PRVEPs) during long periods of stimulation to show whether or not PRVEPs in migraines are abnormal. METHODS: Patients were divided into two groups; Group 1 (migraine with aura; MWA, n=29) and Group 2 (migraine without aura ; MOA, n=32) according to the International Headache Society criteria. PRVEPs were performed in both groups and in healthy volunteers (n=62). PRVEPs were averaged in 100 responses for a total duration of 10 minutes after an initial 3 minutes during stimulation and were analysed in terms of latencies and peak to peak amplitudes of N1-P1 and P1-N2 peaks. RESULTS: Amplitudes of PRVEPs in migraines showed significant increases compared to normal subjects (p<0.001), and amplitudes of PRVEPs in MWA showed significant increases compared to those in MOA (p<0.05). CONCLUSIONS: These results are explained by cortical hypoexcitability and hyper-responsiveness in migraine and by additional cortical hyper-responsiveness (another hyper-responsiveness) in MWA compared to MOA. We suggest that serotonergic and noradrenergic hyperactivity could be responsible for cortical hypoexcitability and hyper-responsiveness in a migraine brain. Another hyper-responsiveness in MWA could also be thought of as some evidence for cortical neuronal abnormality in MWA in addition to serotonergic and noradrenergic hyperactivity in a migraine brain.
